Possibilities of gene identification expertise for the solution of problem on mono- or dizygotic origin of twins were demonstrated. It was shown that DNA printing method makes it possible to differentiate mono- and dizygotic twins in complicated cases. 相似文献

A gas chromatographic/mass spectrometric (GC/MS) procedure is described for the detection and measurement of delta 9-tetrahydrocannabinol, 11-hydroxy-delta 9-tetrahydrocannabinol, and 11-nor-delta 9-tetrahydrocannabinol-9-carboxylic acid in blood, or 11-nor-delta 9-tetrahydrocannabinol-9-carboxylic acid in urine. About 50% of all homicide victims and motor vehicle drivers killed in Bexar County in 1985 were tested for the presence of cannabinoids. Of 130 homicides and 69 drivers tested, blood was analyzed primarily in all but 15 and 3 cases, respectively. In these latter cases, blood analyzed after urine was found to be positive. Of the homicide victims, 44 (34%), and of all drivers, 19 (28%), tested were positive for one or more of the cannabinoids. As a separate group, 16 motorcycle drivers tested had 38% positive as compared with 25% of the other vehicle drivers. Ethyl alcohol was present in 55% of the drivers, and in 63% of the homicide victims. Drugs other than alcohol or cannabinoids were found in 10% of the drivers, and in 12% of the homicide victims. 相似文献

In their critique, Garfinkel, McLanahan, and Wallerstein raise concerns about the representativeness of the authors' sample, benchmark approach methodology, and historical review of guidelines, all of which lead them to discount the evidence presented opposing the cliff-model assumption of father expenditures on children, and to laud instead child support guidelines that give little monetary credit or adjustment for visitation. This article presents evidence that (a) this sample is at most little biased, and remains trustworthy for the main implications presented; (b) although only a beginning, the benchmark approach is highly useful and most of the concerns raised about it are ill founded or implausible; and (c) the historical review suggesting that current guidelines assume zero visitation expenses is indeed accurate for the vast majority of states, according to the foremost authority. Thus, notwithstanding the critique, these findings have merit and importance and should be considered by policy makers. The authors also comment on the additional arguments against continuous and generous adjustments for visitation, finding them based on a weak foundation of evidence and reasoning. 相似文献

Risk of relapse and recidivism makes the failure to take antipsychotic medication as prescribed a significant issue in forensic psychiatry. This question may arise in such contexts as the setting of bail, plea bargaining, the insanity defense, and sentencing. We have reviewed the literature on medication noncompliance in schizophrenia and present here the results, organized by topics relevant for the work of forensic mental health experts. Reported rates of noncompliance vary widely, reflecting major differences in the populations studied and the methods used as well as the complexities involved in defining noncompliant behavior. A noncompliance rate of 50 percent has been attributed globally to chronic patients, both medical and psychiatric. The tendency of significant factors to interact precludes a simple typology of noncompliance. However, environmental security and supportiveness correlate positively with adherence; whereas anxiety, paranoia, grandiosity, depression, and side effects correlate negatively. Clinicians' assessments of whether medication is being taken have proven to be unreliable. Although monitoring by chemical measurement, particularly a radioreceptor assay for urine samples, can be useful, depot injection ensures that prescribed medication is being taken. Less invasive means of promoting compliance are described; psychodynamic and ethical issues to be considered in the monitoring and promotion of compliance over extended time periods are presented. We also probe the link between medication noncompliance and behavioral relapse. The time between default and relapse is most often measured in weeks. Whether due to medication withdrawal or not, the relapse pattern of each individual tends to repeat, allowing its recognition before recidivism occurs. Restarting medication at this stage, especially with a dosage increase, is usually effective. In sum, the forensic mental health expert can now readily use a large and diverse literature to assist with a variety of significant issues. 相似文献
